Original application filed February 1-), 1921, Serial 1%. 444,039. Divided and this application filed May To all whom it may cancer 2t.

Be it known that I, THOMAS W. HoLLnY,

a citizen of the United States, residing at Ranger, in the county of'Eastland and State of Texas, have invented certain. new and useful improvements in lVell-Drilling Rigs, of which the following is a specification.

This invention relates to well drilling rigs and is a division from my copending application filed February 10, 1921, Serial No. 444,030 and the primary object ofthe invention. is to provide a novel means for con structing and arranging the sand reel supporting pedestal and control mechanism upon the standard rig, said means cooperating with the standard rig to permit the adjustment of the sand reel and control mechanism, to suit varying conditions and to eliminate the usual diliiculties experienced in associating the pedestal with the rig and the wear on the pedestal.

It is now common practice to support the sand reel by a shaft received at one end by a tail post and at its other end by a lever carried by the knuckle post, the lever being manually actuated by a sand reel handle and reach connecting the handle and lever. The pedestal or knuckle post is rigidly connected with the main sill by cutting a notch or gain therein for receiving the knuckle post, which not only materially weakens the main sill, but prevents adjustment of the knuckle post in relation to the band wheel.

Further the lever, in the usual construction is generally-made of wood and receives the end of the sand wheel shaft. in the lever for the sand wheel shaft rapidly enlarges making necessary replacement of the pedestal or lever which takes time and is a considerable expensewhen replacement is frequently required.

It is therefore, a prime object of the invention to provide a novel pedestal, and a novel means for mounting the pedestal upon the main Slll whereby the .notchingof the main sill .is eliminated, and whereby ad justment of thepedestal longitudinallyof the sill is permitted, so .asto allow initial adjustment of the sand reel in relation to the band wheel.

A further object of the invention is to provide a novel support for one'end of the sand reel shaft adjustably mounted within the pedestal, so that the-sand reel can be finally adjusted in relation to the said band The hole Serial No. 561,927.

be hereinafter more specifically described,

claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of a portion of the wheel drilling rig showing a pedestal and reel controlled mechanism constructed inaccordance with this invention applied thereto.

a Figure 2 is a plan view of the sand reel portion of the rig.

Figure 3 is a detail view partly in eleva tion and partly in vertical section of the reel and a portion of the control mechanism. Figure 4 1s an enlarged sectional view on i the line 44 of Figure 1 of the drawings.

In the drawings, where similar characters refer to similar parts throughout the views, A designates the main sill, B the sub sill, C the sand reel tail sill and D the mud sills of the rig; E the sand reel, F and G its shaft and pulley respectively; H the band wheel for engagement with pulley G and J the derrick floor all of which may be of the usual or any preferredconstruction. The one end of shaft F may be supported by a tail post or pedestalof the usual construction but in the example shown is supported by a pedestal K of the character disclosed in my co-pending application for patent filed on the tenth day of February, 1921, Serial Number 444,029. The present invention is designated by L as to the pedestal and M as to control mechanism for the reel.

The invention is herein shown as applied to whatis commonly known as the standard rig, in which the sand reel shaft F is dis posed with its axis extending diagonally crosswise the plane of band wheel H, but it is to be understood that the principle of this invention may be applied to other types of rig, without departing from the spirit of the invention. It is' understood that, in

' use of a cable 5, and this is accomplished by -moving-the shaft F so that the pulley G is moved lnto and out of engagement with the band wheel H.

The'particulartype of pedestal or tail 7 post K, shown in Figure 2 of the drawings does not form a part of the present invention, but is more specifically disclosed in my "co pending application for patent hereinbefore referred to. It is shown merely byway of example to indicate" that the shaft F,

.wh'en moved, for bringing the pulley G into and out of engagement with the band wheel 1 H, pivots in bearing 60f the pedestal K,

The pedestal L comprises, broadly, a base 7, a frame 8, and abearin'g block 9 slidable in frame 8. The base has means 10 for securing the base to the main sill A' of the "rig, so that it maybe adjusted longitudinally of the sill, or in other words, in a l prises a pair of base bars 12 arranged in -parallel spaced apart relation, and a con- 'plane' parallel to the plane or band wheel H.

The frame 8' has means 11 for securing it to the base Tand permitting adjustment of the "frame toward or. from the plane of the band wheel H.,. l i

The base 7 in. the example shown comneetion 13, such as-a piece of timber which is secured to the under side of the bars 12, and which may be secured to the bars in any suitable manner, such as by bolts 14 and nuts'1'5; The base bars 12 are preferably formed-of rolled. angle section, thus provid-,

ing a horizontally disposed flange 16, and vertically disposed'fla'nges 17. For a purpose to be subsequently set forth there is provided adjacent each end of flange 16, a perforation 18, and-the vertical flanges 17 are each provided with a series of perforations 19 arranged longitudinally of the :flztnge. The base 7 may 'also'comprise one or more filler pieoes20, which may be interfpose'd between 'the connections' 13 a and the base sill A inorder to dispose the base bars 12 .atthe desired distance above the upper .face of the main sill,"these filler pieces being preferably arranged directly beneath the base bars, as clearly shown inFigure 1 of the, drawings. a

. The means 10 for securing the base to the ,main sill may comprise clamp bars 21 adapt- "ed to engage the under side of sillA, and

, take up rdevices 22, which latter 'may each be-in the form of a rod 23sc rew'threaded' at opposite end portions, and nuts 24 in screw threaded'len'gagement with; these endv por- V tions.

cent its end portions with perforations 25,-

Each clamp bar is provided adjatherebeing one clamp bar for each base V bar, theperforatio'ns 2'5'being aligned with the perforations 18in the base bar. The

rods 23 are thus accommodated in the perrelation, and horizontal guide members 27 secured to the uprights 26 in spaced apart relation. The uprights 26 may be conveniently formed from rolled channel sections, one of which is provided with a vertical slot or opening 28 for a purpose to be subsequently set forth. The guide members 27 may be substantially H shaped in cross section, whereby each member is provided with parallel flanges 29, serving to hold the bearing block 9 against movement laterally of the frame. The guide members may be sooured to the uprights, in any suitable manner, such as bv'bolts and nuts 30 and 31 respectively.

Referring now to the means 11 for securing the frame 8 to the base 7, permitting adjustment of the frame toward or from the plane of the band wheel H, such may consist merely of bolts 32 and nuts 33, although it is desirable to also provide braces 34, connected to the upper portion of the frame as by one of the bolts 30 and nuts 31, and 1:0 the base bars as by bolt 34 and nut 35, these braces acting as struts, since most of the pressure incident to operation of the sand reel, is outwardly, the bearing block. 9 acting somewhat as a thrust bearing where a beveled pulley G- is used. The shanks of bolts 32 may be extended through any selected perforations .19, these perforations permitting of adjustment of the frame 8 to ward or from the plane of the band wheel H.

Bearing block 9 may be formed of a single piece of metal, or may be built up in any suitable manner, it suflicing to show, in the example shown, that the block is provided with an opening 36 for the reception of shaft F, a lining of Babbitt metal or its equivalent 37, being provided in said opening, and the block also having grooves 38 at its upper and lower faces for the recep- 1t tion of the flanges 29. lVhile hut slig movement of the block is nevessary to bring the pulley G into and out of engagement with the band wheel H, the frame 8 is made relatively long so that it is possible to move the bearing block 9 a considerable distance in either uprights 26. This has a material advantage as will be noted hereinafter. since it is not always possible to clamp the base 7v to the main sill in a manner that the shaft E is accurately positioned for engagement of the pulley Grwiththe'bandwheel H.

ends; a sand reel lever 45 on platform J adapted to be "manually actuated; and a reach 46 operatively connecting levers 44 and 45, so that when movement is imparted to lever 45 it will be transmitted through reach 46, lever 44, lever 41 and link 42, to the bearing block 9. It is preferred to provide the arm40 with a plurality of'perforations 47 longitudinally thereof, and to provide apluralityof perforations 48' in spaced apart relation longitudinally of lever 41. Also link 42, may be provided with a plurality of perforations 49, so that the connecting device 50, such as a bolt, Which pivotally connects the lever 41 to arm 40 may be disposed in any of the perforations 47 and 48 selected, for adjustment. Likewise connecting device 51 for the link 42 and lever 41 may be passed through any of the selected perforations 48 and 49, for ad justing purposes, as hereinafter noted. The arm 43 and lever 44 is provided mainly to permit of disposing the sand reel operating lever 45 in the belt house or well within the margins of the platform J, and so as to avoid engagement of the reach 46 with a standard 52 of the band wheel H, which is usually a stock feature. The connection between lever 44 and arm 43 may be by means of a pin or bolt 53 extending through an elongated slot 54 in the end portion of lever 44. The reach 46 may be made up of a plurality of sections: detachably and adjustably connected, as indicated M55, and the end portion of the reach adjacent lever 45 may be provided with a plurality of perforations 56, any one of which may be aligned with any one of a plurality of perforations 57 in lever 45, a bolt 58 serving to pivotally connect the lever with the reach.

It is to be noted that the perforations 47, 48 and 49 permit a wide range of adjustment as to the relative position between the bearing block 9 and the operating lever 45. The relatively long guide bars 27 enable the workmen to quickly assemble the pedestal into operative relation to the main sill by use of means 10, accurate adjustment at such time not being necessary. When assembling the shaft into operative relation with the bearing block 9, the entire frame 8 may be moved toward or from the complemental pedestal K, according to the length of the shaft to be accommodated, this being possible because of the provision of means 11. After the mechanism hasthus been. assembled, it is desirable to adjustthe mecha- ,nism'so'thatthe pulley G will have good frictional, contact with the band wheel H, Soasto not wear the latter.

estal K,"or-by adjustmentof the mechanism M. The link42 extends through the open- 'ing128 in upright 26,which opening isof sufficlent size to permit the l nk to sw ng in-' cidenti to movement oflever 41.

From the foregoing description, it can be seen that a novel well drilling rig has been provided in which the pedestal for the sand reel can be adjustedlongitudinally ofthe main sill of the rig in a novel mannerand the bearing for the sand reel shaft adjusted in respect to the pede'stahbothlongitudinally and laterally" with respect to the band wheel, and novel means for-permitting adjustment of the novel control mechanism for the sand reel.

Changes in details may be made without departing from the spirit or scope of this invention; but,
